I recently bought a '94 Z28 rolling chassis....I'm in the process of putting an LT1 together to go back in it...I got a '95 and put it in and then bought a '93-'94 opti....I don't see how it lines up or gathers timing from the cam....I've owned 6 LT1 cars and this one seems weird for some reason....I'm used to seeing the "clover leaf" on the back of the opti, but it is flat and has a whole in the center with "gears" in it...Will the '95 cam work in the car and what do I need to make it work?...I did get a '95 opti, but I heard there's alot of stuff to go through to make it work...I really just want to use the '94 opti and maybe grind the dowel pin down on the '95-up cam, but i'm still missing something from the back of the opti...Any ideas, suggestions, comments would be greatly apprecaited....Thanks
